They can be, but the hint system is very fair. All puzzles have multiple hints, each more explicit than the last, purchased with in game currency. It's pretty much impossible to get stuck and unable to progress the plot because all mandatory puzzles have hints that are super answer-giving-awayish. Optional puzzles are harder but you can come back to them any time if your stuck. Getting very frustrated with the game requires being particularly stubborn.
LOLL!! I might bug you for help from time to time! o___o
